ORA provides a more complete measurement of IOP after LASIK with a femtosecond laser than GAT because ORA provides greater knowledge of the corneal biomechanics in terms of CH and CRF.

Cancer nanotechnology is emerging as one of the promising strategies combining photothermal therapy (PTT) and photoacoustic imaging (PAI) for the treatment of breast cancer and it has received considerable attention in the recent years because it is minimally invasive, prevents damage to non-targeted regions, permits fast recovery, and involves breast cancer imaging. The present study demonstrates multifunctional biocompatible chitosan-polypyrrole nanocomposites (CS-PPy NCs) as novel agents for photoacoustic imaging-guided photothermal ablation of cancer because of their biocompatibility, conductivity, stability, and strong near-infrared (NIR) absorbance. The CS-PPy NCs are spherical in shape and range 26–94 nm in size with a mean value of 50.54 ± 2.56 nm. The in vitro results demonstrated good biocompatibility of CS-PPy NCs, which can be used in PTT for cancer cells under 808-nm NIR laser irradiation. Tumor-bearing mice fully recovered after treatment with CS-PPy NCs and NIR 808-nm laser irradiation compared to the corresponding control groups. Our research highlights the promising potential of using CS-PPy NCs for photoacoustic imaging-guided photothermal ablation of cancer in preclinical animals, which should be verified in future clinical trials.

In this article, an actively formed dual anchor structure was newly designed and applied to improve the tuning range and mechanical reliability of an RF micro electromechanical system (MEMS) tunable capacitor. To construct the dual anchor structure, metal dimples, which are formed on the centers of hinges, are placed in contact with metal posts before pull‐in occurs, resulting in the formation of second anchors. The measured tuning ranges of the fabricated MEMS tunable capacitors with and without dual anchors were 59.2% and 28.3% at the applied voltage ranging from 0 V until pull‐in voltages of 17 and 9 V, respectively. The fabricated tunable capacitor also exhibited high quality factors of 80.63 and 61.19 at 5 GHz and the applied voltages of 0 and 16 V, respectively. Its size/volume is 1.032 × 1.628 × 0.0089 (H) mm3. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1451–1454, 2015
